三峡工程三斗坪坝址岩石力学研究

The Rock Mechanics Study for the Three Gorges Project at Damsite Sandouping

本文扼要地介绍了三峡工程三斗坪坝址的地质条件,概括了有关的岩石工程问题,即:岩体(石)的物理力学性质,岩体概化模型的研究,岩体天然应力状态和地下水的研究,风化岩体和多裂隙岩体的利用和加固研究,坝基和岩石高边坡的稳定问题,以及库岸滑坡问题。文中简要介绍了30多年来长江科学院为研究解决这些问题进行的试验研究工作,并提出了今后科研工作的建议。

In this paper the geological conditions of the Three Gorges Project at the damsite Sandouping are described and the related rock engineering problems are summraized. These are : physical and mechanical characteristics of the rock mass, the study on the rock mass conceptual model, the nature stress state and the underground water in rock mass, the study on the utilization and reinforcement of weathered and jointed rock mass, stability problems for dam foundations and high rock slopes and landslide problems along the reservoir. Tests and research works conducted by Yangtze River Scientific Research Institute in more than 30 years to solve these problems are briefly introduced and suggestions for further research works are forwarded.
